Energizer CR2 3V Lithium Battery (2 Pack)

The Energizer CR2 is a 3V lithium battery in a compact 27mm x 15mm cylindrical cell, supplied here as a twin pack. Each cell delivers a stable 3V output through its lithium chemistry, making it suitable for devices requiring consistent voltage rather than gradual decline during discharge.

Designed for digital cameras, professional flash units, rifle scopes and night-vision equipment, the CR2 provides the rapid energy discharge these devices need during high-draw moments such as flash recycle or image capture. The compact size fits devices where internal space is limited, and the light 11g weight per cell makes them suitable for handheld and portable equipment where battery weight is a consideration.

Energizer rates the CR2 with a 10-year shelf life when stored at room temperature, allowing spare cells to be kept in camera bags or equipment cases without significant capacity loss. The lithium chemistry maintains voltage output across a wider temperature range than alkaline cells, making the CR2 reliable in both cold outdoor photography sessions and warm indoor studio work. Each pack contains two cells sealed in blister packaging.

What voltage does the CR2 provide?

Each CR2 cell delivers 3V output. Lithium chemistry provides a stable voltage plateau throughout discharge rather than the gradual decline typical of alkaline cells.

What devices use CR2 batteries?

CR2 cells are commonly used in compact digital cameras, professional camera flash units, rifle scopes with illuminated reticles, rangefinders, night-vision equipment, and some high-end torch models.

How long do unused CR2 batteries last?

Energizer rates the CR2 with a 10-year shelf life when stored at room temperature in the original packaging. Actual shelf life depends on storage conditions — heat accelerates capacity loss.

Are CR2 batteries rechargeable?

No. Energizer CR2 lithium cells are single-use and not rechargeable. Attempting to recharge them can cause leakage or rupture.
